One year, after her first bite of this cookie, my DD sighed and said, "Now I know it's Christmas!"
You will need to keep these frozen until needed or they will disappear! I usually make a couple of double batches, 6 dozen is not enough.
Melt the chocolate and shortening together over hot water, cool.
Beat in the sugar until well blended. Add the vanilla.
Beat in the eggs one at a time, mixing well after each.
Sift together the flour, salt and baking powder, and stir into the chocolate mixture.
Stir in the chocolate chips.
Cover the bowl and chill for several hours or overnight.
Divide the mixture in the bowl into halves, then each half into three equal pieces. Each piece makes one dozen cookies. Roll one piece into a log and cut log in half, then each half in half. Cut each small piece into thirds and you will have 6 dozen equal sized cookies.
Roll each piece into a ball.
I always mix these up in November and freeze them raw. Just set the balls on a wax-paper lined cookie sheet and set them in the freezer until they are hard. Now put the frozen cookies into a zip lock bag or rigid storage container.
Now the fun part. If the balls are frozen roll each ball between your palms for a few seconds. Roll each ball in sifted powder sugar to coat thoroughly. Place the balls 2 inches apart on baking paper or lightly greased foil.
Bake at 375°F for 10 minutes. Check after 8 minutes, ovens vary quite a bit. The cookies will be very soft, but will become firm as they cool.
